DescriptionNVD
PMD is an extensible multilanguage static code analyzer. Prior to version 7.22.0, PMD's vbhtml and yahtml report formats insert rule violation messages into HTML output without escaping. When PMD analyzes untrusted source code containing crafted string literals, the generated HTML report contains executable JavaScript that runs when opened in a browser. Practical impact is limited because vbhtml and yahtml are legacy formats rarely used in practice. The default html format is properly escaped and not affected. Version 7.22.0 contains a fix for the issue.
AnalysisAI
Cross-site scripting (XSS) in PMD's legacy vbhtml and yahtml report formats allows arbitrary JavaScript execution when HTML reports are opened in a browser, triggered by analyzing malicious source code containing crafted string literals. Public exploit code exists for this vulnerability affecting PMD versions prior to 7.22.0. …
